METAL SHEET PIMNG.

SPECIFICATION forming part of Letters Patent 1\l'o. 744,847, dated November 24:, 1903.

Application filed March 26, 1903.

To all whom it may concern.-

Be it known that I, HENRY WITTEKIND, a citizen of the United States, residing at Chicago, county of Cook, State of Illinois, have invented a certain new and useful Improvement in Metal Sheet-Piling; and I declare the following to be a full, clear and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

Myinvention relates generally to piling for use 7 in constructing caissons, coder-dams, foundations for buildings, bridges, &c., and more particularly to metal sheet-piling.

My invention has for its object the provision, in a metal sheet-piling in which standard rolled beams are used, of a compound section having angular channels at its opposite sides to receive angular flanges on the sides of the adjoining sections, whereby the edges of the adjoining sections of the piling may be so interlocked as to permit their connection or separation bya relative longitudinal movement.

A further object of my invention is to provide a metal sheet-piling the sections of which may be readily interlocked as they are successively driven, so as to render the piling strong and waterproof and which at the same time will be simple in construction and durable in use.

My invention, generally described, consists in a compound section to form part of the metal sheet-piling, comprising a plate around the opposite side edges of which extend angle-beams and means for spacing the anglebeams from the side edges of the plate, so that channels are formed to receive angular flanges on the sides of the adjacent sections in the piling.

My invention Will be more fully described hereinafter with reference to the accompanying drawings, in which the sameis illustrated as embodied in several convenient and practical forms, and in which-'- Figure 1 is a sectional View of one form of Serial No- 149,609. (No model.)

my improved compound section and the cooperating section of metal sheet-piling; Fig. 2, a View similar to Fig. 1, showing a modified form of myimproved compound section, in which a modified connecting-section is also shown; and Fig. 3, a View similar to Figs. 1 and 2, showing still another modified embodiment of my invention and a modified unitingsection of metal sheet-piling.

Similar reference characters are used in the several figures of the drawings to indicate similar parts.

Referring more particularly to Fig. 1, A indicates a plate of any desired height and width suitable for use in constructing metal sheetpiling. 0 indicates an angle-beam extending aroundone side edge of the plate A, while B indicates a similar angle-beam extending around the opposite side edge of the plate A. D D indicate filler-strips interposed between the plate A and the inner edges of the anglebeams B andO, thereby spacing the anglebeams apart from the plate, so as to form grooves or channels to receive the angular flanges on the adjacent sections, which coop crate to form the metal sheet-piling. Any suitable fastening means may be provided for uniting the angle-beams to the plate A- such, for instance, as rivets d, passing through registering openings in the plate,angle-beams, and filler-strips.

In the modification shown in Fig. 2 the filler-strips are dispensed with, the grooves or channels between the angle-bars B and O and the plate A being formed by offsetting the inner edges of the angle-beams to form flanges D. Suitable fastening means-such, for instance, as rivets cZ-are passed through registering openings in the offset flanges D in the angle-bars and in the plate A.

Referring to Fig. 3, the compound section is shown as consisting in a plate A and angle-beams B and C spaced apart from the plate A so as to form guide grooves or channels, by means of a filler-plate D extending between the plate and the inner edges of the angle-beams.

Suitable fastening devi.ces-' such, for instance, as rivets d pass through registering holes in the angle-beams, plate, and interposed filler-plate.

In each of the several different forms of compound sections above described guide grooves or channels are formed around the sides of a plate to receive angular flanges on the sides of cooperating sections of piling. Various forms of cooperating sections may be employed-such, for instance, as shown in Fig. 1, in which a plate a and channel-beams b and c are united together, with the flanges on the channel-beams extending relatively outwardly. The channel-beams are secured to the plate a by any suitable meanssuch, for instance, as rivets passing through the plate a, near the side edges thereof, and through the adjacent flanges of the channelbeams. The flange on the channel-beam b which is not secured to the plate a extends within the groove formed in the compound section between the plate A and the anglebeam B. It is obvious that a compound section may be interlocked with the disengaged flange on the channel-beam c, in which case the groove formed between the angle-beam C and the plate A on such compound section surrounds the flange on the channel-beam c. It is of course evident that a section similar to that composed of the plate a and channelbeams 17 and c is located at either side of each compound channel-beam, composed of the plate A and angle-beams B and 0, so that the metal sheet-piling comprises a series of alternate similar sections.

In Fig. 2 I have shown a section for uniting the compound sections consisting in two angle-beams b and c, overlapped and secured together so that their disengaged flanges extend in opposite directions, thereby forming a Z-bar, the opposite flanges of which are interlocked with the grooves formed between the plates and angle-beams'of the compound sections.

In Fig. 3 I have shown an integral sect-ion to be interlocked with my improved compound sections, consisting in a plate a having sides 19 and 0 from the outer edges of which extend outwardly-projecting flanges adapted to be inserted within the grooves formed between the plate A and the an glebeam B and 0 It is obvious that any one of the cooperating sections shown in Figs. 1, 2, and 3 may be used in conjunction with any one of the embodiments of my improved compound section. (Shown in Figs. 1, 2, and 3.)

In the use of my invention the several sections are successively driven, the side edge of any desired length. may be readily constructed by driving the desired number of interlocked sections.

From the foregoing description it will be observed that I have invented an improved compound section of metal sheet-piling, comprising a plate around the ends of which are formed grooves by means of angle-beams secured thereto and extending around the opposite ends thereof.

While I have described more or less precisely the details of construction, I do not wish to be understood as limiting myself thereto, as I contemplate changes in form, the proportion of parts, and the substitution of equivalents, as circumstances may suggest' or render expedient, without departing from the spirit of my invention.

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. Ina metal sheet-piling, a compound section composed of a plate, and angle-beams spaced from the plate and extending around the side edges thereof thereby forming channels to receive the side flanges of the adjacent sections of piling.

In a compound section of metal sheetpiling, the combination with a plate, of an angle-beam extending around one side edge of the plate, and a filler-bar interposed between said plate and angle-beam thereby forming a channel to interlock with the adjoining section of piling.

3. In a compound section of metal sheetpiling, the combination with a plate, of angle-beams extending around the side edges of the plate, filler-bars interposed between the plate and each of said angle-beams, and means for rigidly uniting said plate, fillerbars and angle-beams thereby forming channels to interlock with the adjoining sections of piling.

4.. In a metal sheet-piling, the combination with a section composed of a plate and an angle-beam spaced from the plate and extending around one side edge thereof thereby forming a channel, of a cooperating section having an angular side flange adapted to be received within the channel of said first section.

5. In a metal sheet-piling, the combination with a section composed of a plate, and angle-beams spaced from the plate and extending around the side edges thereof thereby forming channels, of a cooperating section having side flanges projectingin opposite directions and adapted to be received within the channels in the adjacent section first described.

6. In a metal sheet-piling, the combination with a section composed of a plate and an angle-beam spaced from the plate and extending around one side edge thereof thereby forming a channel, of a cooperating section comprising a central plate from the opposite sides of which angular flanges project outwardly with respect to each other, such flanges beof, the disengaged flanges 0n saidchannel- Io beams being adapted to interlock with the channels in the adjoining sections.

In testimony whereof I sign this specification in the presence of two Witnesses.

HENRY WITTEKIND.
